Automation and Drives - SCE 2. OPERATOR CONTROL WITH WINCC FLEXIBLE 2.1 System Description Since processes are becoming more and more multi-layered and the demands on the functionality of machines and plants are increasing, the operator needs a high-performance tool for controlling and monitoring production plants. An HMI system (Human Machine Interface) represents the interface between a human being (the operator) and the process (machine/plant). The controller actually controls the process.
Automation and Drives - SCE 2.2 Installation/Deinstallation 2.2.1 System Prerequisites WinCC flexible supports all common PC platforms that are IBM/AT compatible. Although values for a minimum configuration are specified, you should use as a guide the recommended values for an optimum configuration, for WinCC flexible to operate efficiently.
Automation and Drives - SCE 2.2.2 Installing WinCC flexible After all system requirements that have been mentioned are met, install WinCC flexible from the CDROM. Select the scope for installing components and product languages. • • • Standard installation: recommended Minimum installation: to save memory User defined installation: to specify yourself which components and product languages are installed In addition, the required licenses have to be transferred.
Automation and Drives - SCE 2.2.4 Totally Integrated Automation In addition to an HMI system such as WinCC flexible, a complete automation solution includes other components, such as controller, process bus and periphery.
Automation and Drives - SCE 3. PROJECT DESCRIPTION 3.1 Hardware Configuration In our sample program for a color mixing plant, we are using a programming device with the WinCC flexible 2005 Advanced Engineering System and WinCC flexible 2005 Runtime. The color mixing plant is controlled by means of a SIMATIC S7-300. By using a touch panel (TP177B), the operator can operate the process using the graphic operator interface.
Automation and Drives - SCE 3.2 Plant Description T1 Inflow T1 Outflow T2 Inflow T2 Outflow T3 Inflow T3 Container A color mixing plant is controlled with a SIMATIC S7-300 in the automatic or in the manual mode. In the "Automatic“ mode, the three tanks are filled with a two step control. At the minimum level, the inflow valve opens automatically, and after the maximum level is reached, it is closed again.
Automation and Drives - SCE 3.3 Task Definition At the color mixing plant, the program was changed with the programmer each time the mixing ratio changed. Since such changes are not only time consuming, but also dangerous if wrong entries are made, it was decided to expand the color mixing plant with a TouchPanel TP177B. By using the panel, the following requirements are to be met: - 3.4 The color mixing plant can also be operated with the panel.

Automation and Drives - SCE 6 WINCC FLEXIBLE ENGINEERING SYSTEM 6.1 Program Interface The work environment of WinCC flexible consists of several elements. Some of these elements are coupled to certain editors and are visible only if the corresponding editor is active.
Automation and Drives - SCE 6.1.1 Menus and Symbol Bars The menus and the symbol bars contain all the functions you need to configure your operator panel. If a corresponding editor is active, menu commands or symbol bars are visible specific to the editor. If you point to a command with the mouse pointer, you will get a corresponding QuickInfo for each function. When a new project is set up, the symbol bars are positioned at the upper screen boundary as a matter of standard.
Automation and Drives - SCE 6.1.2 Work Space In the work space, the objects of the project are edited. All elements of WinCC flexible are arranged around the work space. Except for the work space, you can arrange and configure all elements according to your own requirements; for example, shifting or hiding. In the work space, project data is edited either in table form (for example, variables) or graphically (for example, a process image).
Automation and Drives - SCE 6.1.3 Project Window The project window is the central control point for project processing. All constituent parts and all available editors of a project are displayed as a tree structure in the project window and can be opened from there. To each editor, a symbol is assigned. With it, you can identify the associated objects. Only those elements are displayed in the project window that the selected operator panel supports.
Automation and Drives - SCE 6.1.4 Property Window In the property window, the properties of objects are edited; for example, the color of picture objects. The property window is available only in certain editors. In the property window, the properties of the selected object, arranged by categories, are displayed. As soon as you exit an input field, the values that were changed are effective. If you enter an invalid value, it is displayed with a background color.
Automation and Drives - SCE 6.1.5 Tool Window The tool window provides you with a selection of objects that you can insert in your pictures; for example, graphic objects and control elements. In addition, the tool window includes libraries with completed library objects, and collections of picture blocks.
Automation and Drives - SCE 6.1.6 Output Window In the output window, system messages are displayed standard in the sequence in which they occur. The categories identify each WinCC flexible submodule that generated a system message. System messages of the category "Generator" are generated, for example, during the consistency check. To arrange the system messages, click on the header of the corresponding column. The output window displays all system messages of the last action.
Automation and Drives - SCE 6.2 Configuring Displays A display can consist of static and dynamic parts. The controller does not update static parts, such as texts and graphics. Dynamic parts are connected to the controller, and visualize current values from the controller’s memory. Visualization can be in the form of alpha-numerical displays, curves, and bars. Dynamic parts also consist of inputs made at the OP that are written to the controller’s memory.

Click on Consistency check of the project. The result is displayed in the output window. 6.5 Transfer Settings and Data Transfer under WinCC flexible In WinCC flexible, the settings have to be made for the transfer. Click on the button Settings for the Transfer. For Mode, select MPI/DP; enter 1 as station address.
Automation and Drives - SCE Confirm overwriting the keyword list. <> If the transfer settings are correct on the panel and in WinCC flexible, the transfer starts now. After restarting the panel, the start picture appears in runtime. Test all buttons for the display change.
Automation and Drives - SCE 6.6 Button END The project can only be transferred again if the panel TP177B is in the transfer mode. When the panel powers up, the loader appears for a few seconds with the button “Transfer“. Before each transfer, the panel would have to be taken off load so that a switchover to the transfer mode is possible. Data is lost in that case; for example, the date and the time of day have to be reset.
Automation and Drives - SCE Under Events, select the function StopRuntime by Clicking on the function. A configured function is referred to in bold print. Under mode, other settings can be made. For our panel TP177B, only Runtime is to be terminated. Save your project and start the consistency check. Note If during the consistency check, lines that are marked blue that contain internal warnings occur, you have to regenerate the entire project first.
Automation and Drives - SCE 6.7 Configuring a Connection So far, we worked in our project without accessing the SIMATIC S7 controller. On our panel, levels are to be displayed and fill setpoints are to be entered. For operator and display objects that access the process values of a controller, first the connection to the controller has to be configured. Here, you specify how and by means of what interface the panel communicates with the controller. Double click on the window Connections.
Automation and Drives - SCE 7 DISPLAY AND OPERATOR OBJECTS Display and operator objects are graphic elements with which process displays are designed. In Runtime, all display and operator objects behave dynamically. In addition, you can make the properties of objects dynamic. One example of this is the graphic of a tank whose liquid level is displayed as varying, depending on the corresponding process value.
Automation and Drives - SCE 7.
Automation and Drives - SCE Note Depending on the operator panel for which you are configuring, some objects from the tool window are not available, or only with limited modes of operation. Objects that are not available are displayed in the tool window grayed, and can not be selected.
